The Meridian trail allows access to Usery Mountain Regional Park from a small trailhead on the west side of Meridian road in Apache Junction. The Meridian trail ends at the Blevins trail. At this point you can return to the trailhead for a 1.8 mile hike or forge further into the park.
Silly Mountain Park is on the edge of Apache Junction and Gold Canyon. It has a few miles of new trails that loop around the mountain. It's a nice hike with kids/pets. I have seen bikers and runners too. Great views of the Phoenix Valley. There is a short nature trail that is ADA accessible.
